 dall, 1908, p. 7. 



Buzzards Bay in neighborhood of Woods Hole, 

 rare. Recorded by Baird in 1871; two speci- 

 mens taken in local trap in 1903 (June 17 and 



25)- 



Parasites: Cestodes (Linton) Dinabothrium sep- 

 taria, Phyllobothrium sp. Copepods Echthro- 

 galeus denticulatus (Verrill and Smith); Pan- 

 darus sinuatus (C. B. Wilson). 



Family CETORHINID^E. 



JCetorhinus maximus (Gunner). Basking shark, 

 bone shark. 



Jordan and Evermann, 1896, p. 51. 



A specimen, apparently of this species, was 

 taken in a trap at Menemsha Bight August 16, 

 1906. It was reported as being 12 to 14 feet 

 long. This shark was identified by Prof. I. A. 

 Field from a description given by Mr. Edy 

 Flanders. It was called a "bone shark" by 

 the fishermen. Another large specimen taken 

 at same point in 1908. Edwards. 



Family SQUALID>E. 



Squalus acanthias Linnaeus. Dogfish (called 

 "horned" or "spiny" dog locally, to distin- 

 guish it from Alustelus).

 Buzzards Bay and Vineyard Sound; compara- 

 tively scarce in the neighborhood of Woods 

 Hole at present, a fact in striking contrast to 

 its pestiferous abundance at some other points 

 of the coast. Formerly so numerous locally 

 that it was the chief source of the "fish guano ' ' 

 produced at the Woods Hole factory. Abun- 

 dant at Nantucket, according to Sharp and 

 Fowler. Taken in May, and again in smaller 

 numbers in October; not taken locally in the

 the run. Edwards. Embryos from Balfour's 

 " B " to 30 mm . in length ; also young " pups ' ' 

 6 inches long, July 2 to 17, 1895. W. A. Locy,

 distribution. Present from April to Octo-

 and seines. Likewise dredged by the Survey 

 in from 6 to 17 fathoms, particularly in the 

 western end of Vineyard Sound; in the Bay 

 dredgings only recorded from stations near the 

 lower end.
